ULO3: Critically assess and implement advanced data pre-processing and
analytics strategies in a software development context, focusing on tasks like data
cleansing, transformation, and feature selection.
ULO4: Design, develop, and evaluate big data solutions using programming
models like Map-Reduce and technologies like Hadoop, tailored specifically to
address software development needs such as DevOps integration and quality
assurance.
Assessment Objective The objective of this assessment is to assess student’s knowledge and practical
skills in working with large-scale datasets and leveraging Hadoop ecosystem tools
and technologies for data processing and analysis.

  Plagiarism and Academic
  Integrity
  At CIHE, we take academic integrity seriously and expect all students to maintain
  the highest standards of honesty and ethical behaviour in their academic work. As
  a student, it is your responsibility to ensure that all your academic endeavors are
  conducted with integrity and in accordance with the principles of honesty,
  fairness, and respect for intellectual property. Please refer to “CIHE Student
  Academic Integrity and Honesty Policy” in the Moodle for details.
  Late Submission Policy An assessment item submitted after the assessment due date, without an

Supporting Materials
All supporting materials for this assessment can be found in Hadoop Files folder in Moodle:
1- A virtual machine has been prepared for you on which Ubuntu and Hadoop have been
installed and configured (Hadoop Virtual Machine). All files related to the virtual machine
can be found in the zip file Hadoop_VM (WMWare) or Hadoop_VM (VirtualBox). You need
to download the Zip file and open it on your computer’s hard drive. Then, you need to
install VMWare Player on your computer and open the virtual machine file.
2- Virtual Machine Tutorial (Part 1 and 2) is a tutorial video on how to use the virtual
machine. It shows step by step on how you can you start Hadoop and run a WordCount
example.
3- Hadoop Tutorial.PDF also provides you with detailed instructions on how to start Hadoop
and run WordCount example.
Instructions
The following file contains user ratings for Amazon products:
Amazon Product Review
(Note: If the link doesn’t work, you can download the file from Moodle. It exists in the
Assessment section).
Each user has rated at least one product. The format of the data file is CSV and contains four
columns: User ID, Product ID, Rating, Timestamp. Rating is from 1 to 5. The timestamps are
unix seconds since 1/1/1970 UTC. For example, the following line of the file
A000681618A3WRMCK53V
B0002Y5WZM
2
1383609600
Is interpreted as follows: User A000681618A3WRMCK53V has rated product B0002Y5WZM, 2/5 at
time 1383609600 (Tuesday, Nov 05 2013 11:00:00, Australian Eastern Daylight Time).
Your task is to use MapReduce programming and find the average rating for each product.
Here is an example of the output:
Product ID
Average Rating
0321732944
0439886341
3.47
4.21
You can choose the output format. However, the required information must be included in
the output. You need to include the output file in your submission.

Deliverable
You need to submit an MS Word or a PDF file which includes the following items: –
The source code for map and reduce function (copied/pasted into the MS Word or PDF
file; no separate file is needed). – – – –
The output file.
Enough screenshots on the steps taken to get the program running.
Screenshots for the output generated by the program. The student’s name must be also
part of the printed information. Annotate all screenshots with brief descriptions (one line
or two is enough).
In all screenshots, the date and time of the computer must be clearly shown in the
corner (look at the sample below). Make sure the date and time of your computer is
correct.
A section for discussing the potential benefits of your project for Amazon. You need to
explain how Amazon can make informed decisions based on the results of your project.
This section must be 450 – 550 words.
Note: In order to receive a mark for your submission, it is mandatory to present a demo of your
project to your lecturer during week 12. Failure to do so will result in a zero mark for your
submission. The lecturer has the discretion to adjust team contributions based on individual
contributions to the demo. It is important to demonstrate your active participation and
contribution to the project during the demo to ensure fair grading and assessment.
